Opera mini is an app which uses comparatively less data but do not have that much features. It is a small app and uses less R.A.M memory making it ideal for phones which have less R.A.M. memory. Recenetly the devolopers have added the ’Add block feature in it which protects the users data from wastage of data on unwanted advertisement. Beside this, many mobile networking companies provide free facebook and somtimes free wikipedia in it. That’s why it is extremely economic. However many sites are extremely hard to be visited by opera mini. And some websites do not work well when visited by it. But if inspite of this problem the app is really good for those who want to spend their data economically.
